2005 Buick Rainier Problems

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

I had a new battery installed and since the air condition only blows out on my feet. I have heard that this is has been an issue with several owners. Have you run across this and any ideas how to fix it? (Fuses have been checked, and the battery has been disconnected and reinstalled)

It stops ok, but not as good as my rendezvous. Rainier has anti lock and traction control Rainier does not.

I have a 2004 Rainier. Purchased with 50K miles. I had no major issues until last year. The air suspension that causes the vehicle to adjust failed. This cost was around 600.00. This past weekend my shifter cable broke. I'm unable to shift into any gear. Cost quoted: 235.00 with labor.

I have had suspension problems, gas gauge problems and now thermostat problems. I have replaced the temperature sensor which caused temperature to jump all over the place. Started out stuck at 50 degrees, now climbs to 120 degrees. Problem is the air conditioner stops working when reading changes radically, up and down.
